Improvement in carpet-beaters



UNITED STATES PATENT QEETGE.

WILLIAM G. MOWRY AND CONRAD PULIS, OF NEW YORK, N. Y.

IMPROVEMENT IN CARPET-BEATERS.

Specification forming part of Letters Patent No.1140,525, dated July l, 1873; application filed May 24, 1873.

To all whom it may concern:

Be it known that we, WILLIAM G. MOWRY and CONRAD PULIs, both of the city, county, and State of New York, have invented a new and Improved Carpet Beater; and we do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing- Figure l represents a longitudinal vertical section of our invention. Fig. 2 is a plan or top view of the same, partly in section.

Similar letters indicate corresponding parts.

This invention relates to a carpet-beating machine in which one or more beaters are arranged over an elastic supporting-bed. rIhe beaters turn on a common shaft vor rod, and are exposed each to the action of a spring and of a cam, so that each is raised by its cam and thrown down by its spring. The tails of the beaters are bifurca'ted, and the cams act upon the upper prong in raising the beaters, and they catch up against the lower prongs to prevent the beaters from striking too hard on the elastic bed if the carpet should be removed or should not extend across the entire width of the bed. The front ends of the beaters are fork-shaped, so that they cover the largest possible ground of the carpet and that their blows come close together. The elastic bed consists of a series of spiral springs fastened in common rails and arranged in pairs, the spring in each pair being connected to each other by a cord or piece of webbing.

In the drawing, the letter A designates a frame, of wood or any other suitable material, which forms the bearings for a rod lor shaft, a, on which are mounted the oscillating beaters B, (one or more.) Each of these beaters is subjected to the action of a spring, b, which may be of any suitable form or material, and which has a tendency to throw its beater down upon the elastic bed G. The

' tail end of each beater is bifurcated, its upper prong c being exposed to the action of a cam, d, which is mounted on a shaft, e, to which a revolving motion can be imparted by hand or any other suitable power. Said cam is so shaped that when the shaft is turned in the proper direction the beater will be raised against the action of its spring, and when the cam releases the prong c the beater dies down and the lower prong f ot its tail catches up against the cam, so as to prevent the beater from striking the elastic bed too hard. The elastic bed O consists of a series of spiral springs, g, which are secured in common rails h, and which are arranged in pairs, the spring in each pair being connected by a cord or piece of webbing, (See Fig. 2.) The rails h are fastened in the frame A, and they are equal in length to the width of the widest carpet that may have to be cleaned.

The carpet is passed over a roller, j, and

y over the elastic bed to the drawing-rollers k l,

which are on the end of the elastic bed opposite to the roller j, and which are dra-wn together by spiral springs m, so that the carpet, on being placed between them, is rinly clamped. The roller k receives a slow revolving motion by belt or other connection with the drivingshaft e, and as this shaft is turned the carpet is slowly drawn over the elastic bed. At the same time the beaters are successively raised and allowed to descend and the carpet is eX- posed to a series of sharp quick blows, which readily free the same from dirt or dust. Close to the roller j in front of the elastic bed is situated a brush, D, which receives a revolving motion from the driving-shaft, and which -Inaterially assists in cleaning the carpet from dust.

The outer ends of the beaters are, by pret"- erence, made fork-shaped, (see Fig. 2,) so that the same cover as much ground as possible, and comparatively few beaters are sufficient to cover a wide carpet.

In practice the beaters will be made in sections, the outer ends being fitted into sockets, as indicated in Fig. 1, so that they can be taken out and replaced by others if they should become worn.

If desired, the beaters may be arranged transversely to the bed and two sets of beaters may be employed operating from opposite sides.

What we claim as new, and desire to secure by Letters Patent, isM

l. The recoil prong f on the rear end of the rollers 7c l, substantially as shown :m dearnl of a beater, B, in combination with a cam, d, and spring b, constructed and opera-ting substantielly in the manner set forth.

2. The elastic bed G constructed of spiral springs g arranged. in pairs, and connected by cords or pieces of webbing, in combination with beaters B, revolving brush D, and feedscribed.
